It is an alloy material with high high-temperature strength and resistance to high-temperature oxidation. It possesses high yield strength, creep strength, and rupture strenth below 650°C, along with good workability and satisfactory weldability.
Mainly used for turbine engine combustion chamber components operating below 800°C, and other high-temperature components requiring oxidation resistance below 1100°C bsubjected to very low loads.
